soc/intel/tigerlake: Fix processor hang while plug unplug of TBT device

Port 9c348a7b7ea3 "soc/intel/alderlake: Fix processor hang while plug
unplug of TBT device" from
Alder Lake to fix a similar issue present on Tiger Lake:

```Processor hang is observed while hot plug unplug of TBT device. BIOS
should execute TBT PCIe RP RTD3 flow based on the value of
TBT_DMA_CFG_VS_CAP_9[30]. It should skip TBT PCIe RP RTD3 flow, if
BIT30 in TBT FW version is not set.

BUG=b:194880254
